What is the operational draft with engines raised (DIW)?

• A. 1 ft 10 in
• B. 2 ft 0 in
• C. 2 ft 9 in
• D. 1 ft 8 in

Answer: (A)

Operational draft with engines raised is the water depth the boat needs to float safely when the engines are lifted up. Raising the engines reduces the hull’s depth in the water, so the draft becomes shallower than with engines down. For the 29' RBS II, the published value for this condition is 1 ft 10 in, meaning you can operate in as little as about 1.83 feet of water with the engines raised. This is the figure you’d rely on when planning shallow-water operations. The other depths would correspond to different engine positions or loading scenarios, not the DIW.
